Ammitsu launched the manga in Kodansha’s Bessatsu Friend magazine in July 2017, and Kodansha published the manga’s ninth compiled volume on Friday.
The October issue of Kodansha’s Bessatsu Friend magazine revealed on Saturday that Ammitsu’s Ran the Peerless Beauty (Takane no Ran-san) manga will end in four chapters, including the chapter published on Saturday.
If the manga does not take a break it should end in the January 2021 issue, which will ship in December.
